An Interview Dr Wischhusen, Director of XRG Simulation, the 400th participant in Clean Sky
Questions & answers
Stefan, could you briefly present XRG simulation ?
XRG Simulation GmbH is a SME located in Hamburg, Ingolstadt and Bremen (all in Germany). The company was founded in 2005 by two engineers and myself, all from Hamburg's University of Technology. Our activities focus on energy system simulation (e.g. aircraft systems, automotive systems, buildings, power plants, etc.) and related simulation products. We currently employ 14 staff.
What are your areas of expertise ?
We use and develop flexible and open simulation software (e.g. Modelica) for simulating virtual prototypes of new or modified existing products. Our customers (such as Airbus Operations, Daimler, Audi, Volkswagen and so on) use such models and their simulation results to gather information for design decisions (e.g. what components to select for efficient air conditioning systems and so on). Our main topic is simulation of air conditioning systems but also system cooling (e-vehicles) and very special: water accumulation of aircraft insulations. Furthermore we develop software for mathematical system optimization.
What projects are you involved in Clean Sky ?
We are involved in the Systems for Green Operations (SGO) ITD to model medium properties for refrigerant and humid air which are required to model environmental-friendly air conditioning systems. Simulation results are then further exploited to help making design decisions. Furthermore, the outcome will be available as open-source.
You have received the 400th participants award during Paris Air Show. Nice surprise no ?
We were of course particularly proud for this nice award but also because we are part of the Clean Sky family, with most of the aeronautical players, big or smaller, working together to reach common objectives, from large aircraft to regional to rotorcraft.
Why is XRG, a 14 staff SME, involved in research ?
We do research because we like to develop future products or promote services by demonstrating our expertise. Moreover, we found that our skilled employees gain motivation if they can do challenging research from time to time. And our cooperation with several universtities (Hamburg University of Technology, Technical University of Dresden, RWTH Aachen, Technical University of Braunschweig and University of Rostock) contributes to maintain our skills at the forefront of innovation .
